Both are converted pitchers -- Baez from third base, Jansen from catcher. Both are primarily one-pitch relievers -- Baez with his fastball, Jansen with his cutter.

Mattingly said he still wants Baez to refine his secondary stuff, add something "softer that goes down," but the manager has been pleased by what he's seen out of the 26-year-old this month. In two August stints with the Dodgers, Baez has thrown seven scoreless innings, allowing just four hits and walking two.

"He looks like a guy who has a good chance to be a part of what we do. If not this year, then moving forward," Mattingly said. "Right now, he's growing up. He's getting better. We'll take it for what it is."
